CAN-SOLDERING MACHINE.

SPECIFICATION fo:ming part of Letters Patent No. 353,420, dated November30, 1886.

Application tiled June 5, 1886. Serial No. 204,270. (No model.)

To all whom t may concern:

Beit known that l', Divin M. MONROE, a citizen of the United States,residing at Baltimore, inthe State of Maryland, haveinvented certain newand vuseful Improvements in Can- Soldering Machines; and I do declarethe following to beafull, clear,and exact description of theinvention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and `to the letters and figures of reference marked thereon7 which forma part of this specification.

My invention relates to improvements in can-soldering machines, in whichthe gaging devices are mounted on arotary table and actuated by themovement of the said table, as illustrated in the accompanying drawings,in which- Figure 1 is a side elevation of the machine; Fig. 2, a topView ofthe same; Fig. 3, a detailed vertical section through themachine, with one of the gaging devices shown in full; Fig. 4, a topdetail view ofl the rotary table, with aportion broken away, showing thegaging devices and mechanism by which they are operated. Fig. 5 is anend view ofthe gaging device, showing how the cylinder is secured to thestandard.

Similar letters refer to similar parts throughout the several views.

The letter A designates the frame of the machine provided with thevertical shaft a,which is secured thereto in any suitable manner. Theframe A may be made sufficiently high to rest on the floor, or only ofaheight to be placed on an ordinary bench. On this frame and around theshaft a freely rotates the table B, which may be moved in eitherdirection to suit the operation or circumstances; 'and it consists of acylindrical plate, b, on which are secured the gaging devices O,andradial arms b',

secured to the hub b2, or cast integral therewith In this case sixradial arms and gaging devices are indicated, though any number may beused.

The can-body gaging devices O consist of a base-plate, c, provided withthe standards c', which have circular openings concentric with eachother. The said openings determine the size of the can-body, as they arebored out to correspond with the diameter of the can-head or ends. Inthesaid circular openings is placed the expanding-cylinder, consistingof two parts, D D, secured to one of the standards o only by the platesd,which extend across the standards, and are secured thereto by means ofthe screws d', which pass through the slots cl2 therein and are threadedinto the standards, permitting the parts of the cylinder D D to be movedtoward and from each other. The said cylinder parts D D are forcedoutward by the wedge E, placed therebetween, which extends toward thecenter of the table, and is provided with thejaw @,in which is pivotedthe roller e',and

on which is pivoted asecond roller, e, coaxial with the nist-mentionedroller. These rollers come in contact with the cams F and G alternately,thereby reciprocating the wedge by which the two parts D D of thecylinder are moved toward and from each other.

The cam F is secured to the shaft @,aud consists ofa circular portion,f, which forces and holds the wedge yE outward during nearly the wholerevolution as the table rotates, and an eccentric part, g, which permitsthe wedge to be withdrawn by the roller e2 coming in contact with cam G,which partly withdraws the wedge from the cylinder, and thereby permitsthe parts of the same to approach each other. At this point in thetables rotat-ion the canbodies are inserted and removed.

The cam G is secured to the one F by means ofthe arm g', which, in thisinstance, is'cast integral therewith by means of the screw g, or in anysuitable manner, soas to come in contact with the roller c2 as the tableis rotated, thereby automatically operating the gaging device by therotation of the table. As the wedge E is withdrawn one end of the partsD Dfof the cylinder are drawn together by the springs h, secured theretoby suitable pins projecting therefrom, and the other end lby means ofthe yoke z', secured to the wedge E, acting on the angular orwedgeshaped projection 7c. Immediately over the said yoke mechanism andextending across the standard c' is arranged the plate l, which preventsany flux rom fouling the mechanism thereunder.

The top portion of the standard c is cutaway to form the opening c2, atwhich point the IOO seam is placed, thereby permitting the soldering to.be performed. To one side of the said opening c2 is arranged the guideM, which is provided with the slots m, by which it is secured to thestandards by means of the screws m', and is thereby permitted toreciprocate vertically, the spring m pulling it downward. Vhen theunsoldered can-body is placed on the expandingcylinder and expanded intoform, it comes in contact with the guide'M, and the said guide, beingyielding, adjustsitself to the suface of the can-body, forming a guidefor the soldering-tool, and also retaining the solder and the flux inits position, and, further, holding the overlapped edges of the cantogether.

To the guide M is secured the arm m3, which is provided with theprojection m4. r['his arm, together with the spring m', serves tooperate the said guide automatically, the guide M being raised at theproper time by the projection m4 of the arm m3 coming in contact withthe inclined surface of the lifter Z, which lies in the path of theprojection m4, and thereby raises the guide M and permits the removal orinsertion of a can-body. The said guide returns to its position ofpressure upon the canbody by means of spring m when the projection m*has passed over the lifter Z'.

The plate L is secured rigidly to the shaft a, and forms a support forthe lifter Z by means of the bracket Z3, whichis bolted to the saidplate,and the rod Z, carrying the lifter Z. The bracket Z3 is providedwith the slot Z4, in which the rod Z2 is secured by means of the nutsZ5, which permit the adjustment of the lifter Z, whereby the lift of theguide M is controlled to suit any size can. The plate Lfurther servesthe purpose of a shelf for holding the tools of the operator, and formsa shield for the machinery thereunder.

The manner of operating the device is as follows: The gaging devicewhich is to receive the unsoldered can-body is placed in a positionwhereby the roller e2 will be in contact with the cam G and the roller ein contact with the cut-away portion g of the cam F, whereby thewedgeEis in its outward position and the expanding-cylinder contractedby means of the springs h at one end of the said cylinder and the yokez'and inclined edges of the projection K at the other end of the cylinder.In this position of the gage the projection m4 of the arm m on the guideM will be in contact with the lifter Z, and the guide M thereby raisedfrom the cylinder. The cylinder D being contracted and the guide Mraised, the unsoldered can-body is placed, with its seam upward,over thecylinder C, within the space between the said cylinder D and the innersurfaces of the standards c. The table B, carrying the gaging device, isnow moved from this position, whereby the roller e willbe carried pastthe cam G and the roller e broughtin contact with the enlarged orconcentric portion fof the cam F, thereby forcing the wedge E inward,expanding the cylinder D, and pressing the canbody tightly against theinner surfaces of the standards c', and thus insuring a uniformity inthe size and shape of the can-body. In moving the gaging device from thefirst position the projection m4 of the arm ms of the guide Mwill havepassed the lifting-plate Z, and the guide M will be brought in closecontact with the can-body by means of the spring m', thereby holding theseam together during the process of soldering and cooling., In thissecond position the seam of the can-body is soldered by an operator inthe usual manner with a hand copper. As represented by the dotted linesin the drawings, the apparatus is provided with six gaging-cylinders.The table B is revolved in one direction, and by the use of the sixgagingcylinders sufficient time is permitted after soldering to allowthe solder to cool before the gagingcylinder reaches the first position,when the completed can-bod y is removed from the cylinder and anunsoldered one placed, as before stated.

Having described my invention and the manner of operating, what I claim,and desirek to secure by Letters Patent, is`

1. In a can-bodyseaming machine, the combination of the rotary table B,the can-bodygaging devices mounted on the table, the shaft a, the cam F,and means to expand the cylinder D, whereby the rotation of the tablemoves and successively expands the body-gaging devices, as set forth.

2. rlhe combination of the rotary table B, the expanding-cylinder D, thestandards c', the wedge E, the yoke i, the angular projection k, and thecam G, for the purpose set forth.

3. In a can-body-seaming machine, the combination of the rotary table B,a series of complete gaging and clamping devices mounted on and arrangedto rotate with the table, each comprising the standards c', theexpandingcylinder D, and a guide, M, means to expand and contract thesaid cylinder and to operate said .clampingvguide, jointly arranged tobe automatically operated by the movement of the rotating table B.

Il. The combination of the rotary table B, the expanding-cylinder D, thestandards c', the wedge E, the cam F, and the cam G, for the purpose setforth.

5. The combination of the rotary table B, the standards c', theexpanding-cylinder D, means to expand the cylinder, the clamping- `guideM, the projecting arm m3, and the lifting-plate Z', for the purpose setforth.

In testimony whereof I afx my signature in presence of two witnesses.
